Motor Contactors

Understanding Motor Contactors

A motor contactor is designed to handle the high electrical currents required by motors. This robust, automated switch ensures safety and efficiency in both industrial and commercial systems.

Key Features of Motor Contactors:

• Remote Control and Enhanced Safety
  This device enables remote operation of your equipment from the electrical panel, which is especially beneficial for hard-to-reach installations.
• Protection Against Overloads and Short Circuits
  Paired with a circuit breaker or thermal protection relay, a three-pole contactor continuously monitors the electrical circuit, cutting power if an issue arises.
• Process Automation
  For businesses seeking automation, our motor contactors integrate seamlessly into your systems, aided by their auxiliary contacts.
• Energy Efficiency
  The latest models optimize energy consumption by reducing peak loads during startup.

Applications and Versatility

While commonly associated with industrial environments, motor contactors are versatile and suitable for various applications, including:

• Heating, ventilation, and air conditioning (HVAC) systems
• Pumping systems
• Elevators (for gradual motor startup and emergency stop functions)
• Complex domestic equipment

Leading electrical brands like Schneider Electric offer motor contactors for a wide range of uses. For example, Schneider's TeSys series provides solutions for both three-phase motors in industrial installations and smaller motors in commercial or residential settings.

Different Types of Motor Contactors

Selecting the right motor contactor depends on several technical and environmental factors. Here's what to consider before purchasing:

• Electrical Specifications
  For your three-phase motor, it's crucial to verify the supply voltage and the maximum current the contactor needs to handle.
• Type of Use
  If frequent starting is expected, a traditional electromechanical contactor is recommended. For quieter, wear-free operation, a static contactor may be more suitable.
• Installation Environment
  Protection ratings, such as IP55, offered by brands like Schneider Electric, Siemens, or ABB, are essential for demanding industrial conditions. For more complex setups, opt for models with auxiliary contacts to ease integration into your electrical panel.

At One-Elec, we specialize in professional electrical equipment and only offer CE- and UL-certified motor contactors. Our range includes three-pole contactors for all your industrial automation needs, with rapid delivery available from stock.

Our Motor Contactor Ranges: TeSys from Schneider Electric

Schneider Electric's TeSys K, TeSys D, and TeSys Giga series cater to a variety of applications, from standard industrial needs to the most challenging environments.

At One-Elec, we stock a wide selection of motor contactors, from 6A to 800A, available in three-pole (3P) and four-pole (4P) configurations. We also offer various coil supply voltages, a key factor in product selection.

• TeSys K: Compact, Efficient Contactor (6 to 16A)
  In stock and ready for fast delivery, the TeSys K is ideal for small industrial systems. Its quick DIN rail mounting and power rating up to 7.5 kW make it a preferred choice. Our top-selling model, the LC1K0610B7 (three-pole, 2.2 kW), is perfect for everyday use.
• TeSys D: Versatile and Robust (9 to 115A)
  Popular in industries and HVAC applications, the TeSys D is known for its versatility. With integrated auxiliary contacts and compatibility with our range of thermal relays, it’s a safe bet for motors up to 75 kW. Our top sellers include the LC1D09P7 for up to 9A and the high-power LC1D50AP7 (50A).
• TeSys Giga: High-Performance for Heavy-Duty Applications (115 to 800A)
  Built for intensive industrial environments, the TeSys Giga can operate in temperatures up to 60°C. With a power rating of up to 450 kW and a universal 100-250V AC/DC coil, our flagship LC1G1154KUEN (250A) meets the most demanding requirements.

Why Choose a Motor Contactor Over a Relay?

A three-pole motor contactor offers two key advantages over a standard relay: it can handle higher power levels and is better suited for frequent starts of three-phase motors. For safe installation, we recommend leaving the DIN rail mounting to a qualified electrician, who will place it in a suitable enclosure.

Protect Your Motor with Schneider Electric Thermal Relays:

• For TeSys K: Opt for the LR2K series, perfect for direct mounting.
• For TeSys D: Trust the LRD relays with extended setting ranges.
• For Industrial Applications: The LR9G series, developed specifically for the TeSys Giga, offers exceptional precision.

All our Schneider Electric motor contactors and thermal protection relays are in stock and ready for immediate delivery, ensuring your equipment stays protected.
